Stromal cells are connective tissue cells of any organ, for example in the uterine mucosa (endometrium), prostate, bone marrow, and the ovary. They are cells that support the function of the parenchymal cells of that organ.Fibroblasts and pericytes are among the most common types of stromal cells.The interaction between stromal cells and tumor cells is known to play a major role in cancer growth and progression.In addition, by regulating locally cytokine networks (e.g. M-CSF, LIF), bone marrow stromal cells have been described to be involved in human haematopoiesis and inflammatory processes.ertain types of skin cancers (basal cell carcinomas) cannot spread throughout the body because the cancer cells require nearby stromal cells to continue their division. The loss of these stromal growth factors when the cancer moves throughout the body prevents the cancer from invading other organs.

Major tributaries in the lower section are the ARKANSAS, RED, and White rivers, all flowing from the west. The Mississippi enters the Gulf of Mexico (see MEXICO, GULF OF) about 160 km (100 mi) downstream from New Orleans, through a 26,150-sq km (10,100-sq mi) delta. Because almost 550 million metric tons (500 million U.S. tons) of sediment are deposited annually, the delta extends about 91 m (300 ft) each year.
